🐳 Docker Development

Build and run a development environment with live file mounting:

# Build the development container
docker-compose -f docker/docker-compose-php8-dev.yml build

# Start the containers
docker-compose -f docker/docker-compose-php8-dev.yml up

# Access at http://localhost:8080

Changes to your local files are immediately reflected in the container.

⚙️ Configuration

Environment Variables

WebCalendar supports containerized deployments via environment variables:

SetEnv WEBCALENDAR_USE_ENV true
SetEnv WEBCALENDAR_DB_TYPE mysqli
SetEnv WEBCALENDAR_DB_HOST localhost
SetEnv WEBCALENDAR_DB_DATABASE webcalendar
SetEnv WEBCALENDAR_DB_LOGIN webcalendar
SetEnv WEBCALENDAR_DB_PASSWORD "your_secure_password"
SetEnv WEBCALENDAR_MODE prod

Add these to your .htaccess file or web server configuration.

Database Support

• ✅ MySQL / MariaDB (recommended)
• ✅ PostgreSQL
• ✅ SQLite3
• ✅ Oracle

🧪 Testing

Run the test suite with PHPUnit:

# Install dependencies
composer install

# Run PHPUnit tests
cd tests; ./run_unit_tests.sh; cd ..

# Syntax check all PHP files
cd tests; ./compile_test.sh; cd ..

🏗️ Building from Source

WebCalendar includes all required dependencies in the release (primarily in the pub/ directory). You do not need to run Composer unless you are adding or updating dependencies.

If you need to modify dependencies:

# Install PHP dependencies (only needed for adding/updating dependencies)
composer install

# Copy vendor assets to project directories
make

Note: The Makefile requires Linux (uses sha384sum).

🔌 External Application Integration

WebCalendar can integrate with external systems for user authentication and configuration:

User Integration

Create a bridge script in includes/user-app-yourapp.php:

// Implement required functions for authentication
function user_valid_login($login, $password) { ... }
function user_get_users() { ... }

See user-ldap.php and user-app-joomla.php for examples.

Configuration Integration

Create includes/config-app-yourapp.php to override settings dynamically.
